A staphyloma refers to an abnormal protrusion of uveal tissue through a weakened area of the sclera or cornea, which can occur due to injury, disease, or inflammation. This condition can manifest in various forms, depending on the location of the protrusion within the eye. There are five primary types of staphylomas: anterior segment staphylomas, which affect the cornea and surrounding scleral tissue; intercalary or limbal staphylomas, located at the junction of the cornea and sclera, often leading to complications such as secondary angle closure glaucoma or corneal astigmatism; ciliary staphylomas, found near the ciliary bodies; equatorial staphylomas, which occur in areas associated with vortex veins; and posterior or macular staphylomas, typically identified at the back of the eye through ophthalmoscopy, often in patients with myopia. The procedure described by CPT® Code 66220 involves the surgical excision of the protruding uveal tissue, followed by the closure of the scleral defect using sutures. This repair aims to restore the integrity of the sclera and prevent further complications associated with staphylomas.
